Yes.

use an apple).
I'm still a little confused by this. In Gentoo at least, yaboot does not
require a /boot partition, but it does require the apple bootstrap
partition. This is created by using the 'b' command in mac-fdisk, which
creates an 800k HFS partition. Once created, mkofboot is run to format
the bootstrap partition and copy the yaboot files to it. This is the
location where I put the grubof.modules and grub.cfg files.
For grub to work, does this partition need to be larger and then mounted
as /boot in Linux?
Or do I need a separate /boot partition, but it must be an HFS partition?
Can I see your /etc/fstab and partition map? It might be easier for me to
just duplicate what you have. Once I get it working, I can figure out
exactly what the requirements are. For what its worth, I'm setting this
up on a MacMini with 256MB. Not sure if that should make a difference.
I did try setting up separate /boot and /boot/grub partitions, but didn't
think these needed to be HFS. I assumed that once grub was running from
the bootstrap partition it was no longer neccessary to stay within HFS.

but I'm having some difficulty figuring out the organization as I poke
around. Would the documentation for grub legacy help? Is there some
general information floating around that I haven't found yet?

Have you looked into this yet? I was hoping to dig through the code
before sending this email :) I feel like I'm doing something
fundamentally wrong and it might be easier just following the logic..
Thanks,
